Here are 15 tips for growing your startup's audience on the three top social networks, starting withstrategies that are common to all of
them:

1. Create strong social profiles and pages.

The starting point for growing your audience on any social network is strong profiles and pages for your social accounts.

This requires including branded cover photos and profile photos. It also requires filling out all of your details. On Twitter, that's as simple as a
160-character bio, website link and location. Facebook wants a short description, website link, address and phone number.

In short, fill out as many fields for your social profiles and pages as you can.

Next, share a few updates (five to 10) before you start your quest to build an audience. This will give people who visit your social accounts a reason to
follow you. If you don't know what to post, do the following:

2. Share quality content.

Even before your startup gets going fully, start building your audience on most networks by sharing content your target audience will enjoy.

For example, if you have a startup for a Facebook marketing tool, start sharing content about Facebook. That could mean blog content, podcasts, videos,
presentations and infographics created by you or by others.

Make sure that everyone you communicate with via email knows about your startup, by adding links to your top social accounts in your email signature.

You can do this using small square social network icons or standard text links. Use services like WiseStamp to
create professional signatures with your social links.

6. Cross-promote your social accounts.

Already have a large audience on one account? Ask its members to connect with you on another. That will be as simple as sending a tweet to your Twitter
followers asking if they are on Pinterest. If they are, they should follow you there, too.

Look for opportunities to link from one social account to another. Pinterest, for example, will allow you to link to Twitter and Facebook. Woobox, a Facebook app maker, has apps that enable you to add tabs to your Facebook page for Twitter, Instagram and
Pinterest for free.

Here are tips specific to Twitter:

7. Follow your target Twitter audience and engage with them.

Twitter allows you to follow up to 5,000 people. You can follow more after people start to follow you. When you follow people on Twitter, they get a
notification that they are being followed. In addition to following people, start chatting with them.

Use Twitter Search to find people that match your target audience. Twitter will search keywords in people's bios as well as their tweets. When you see a
tweet from someone that you can reply to, do it. If people like your reply, they just might follow you back.

8. Use Twitter advertising.

If you have an advertising budget, try Twitter advertising. Twitter will promote your account to your target audience members to encourage them to follow
you.

Here are tips specific to Facebook:

9. Use your Facebook page to “like” other pages.

If you click on the drop-down arrow next to your photo at the top right of your Facebook dashboard, you have the option to use Facebook as your page by
selecting it from the list.

This will enable you to “like” other Facebook pages as your page and comment on them. Find pages where your target audience are engaged and start
communicating with them through your page.

Facebook has a setting that you can enable to allow others to follow your personal profile. Any public updates you share will be shared with your followers
in the news feed without your having to accept them as a friend.

This will help you grow an audience that you can promote your business to while keeping your private things private.

11. Participate in Facebook groups.

Another way to utilize your personal profile on Facebook is to engage in groups related to your niche. Find groups in which your target audience would be
interested, join them and start engaging in the discussions.

As happens with Twitter, when you follow other people on Instagram, they will be notified.

You can find your target audience by searching for hashtags they would likely use when they post on Instagram. Then follow people and engage with them by
commenting on their photos and videos in the news feed.

13. Use hashtags on Instagram.

When you share photos and videos, be sure to use hashtags in your captions. Hashtags are used by Instagram users to find visual content on specific topics.

As people come across your photos and videos in a hashtag stream, they will be able to click a button next to your name to follow you.

Here are tips specific to LinkedIn, which is great for B2B connections:

14. Participate in LinkedIn groups.

LinkedIn groups are great for engaging with other active LinkedIn members. Participate in the discussions and provide valuable answers to get people to
want to connect with you.

LinkedIn allows members to post blogs, and some of those members have thousands of followers. Find people in your niche with lots of followers, follow
their latest posts and engage with your target audience in the comments of those posts.
